I have used this as a test. I give the first page to students to make them prove they have memorized the formulas. Then I grade it, let them make corrections, and give it back so they can use it on a Unit Test.I don't make them memorize the material on page 2 for the Identities Test I give.Page 3 is the answers to the identities they are tested over on page 1.Check out my full courses and other trig resources too!
